And object is 20 cm from the lens. The image from 6.66667 cm from the length. What is the focal length of the lens? Use the thin lens equation
Answer:
5
Explanation:
The object distance Is 20 I'm
The image distance is 6.666
Therefore the focal length can be calculated as follows
1/f = 1/20 + 1/6.66
= 6.66+20/133.2
= 26.66/133.2
1/f= 26.66/133.2
f = 133.2/26.66
= 4.99
= 5
Hence the focal length is 5
Why are airports, trains, cruises , and bus stations often considered the highest targets for biological warfare?
Answer:
a combination of large groups of people, and they are all travelling- which increases the spread.
Answer:
The reason airports, trains, cruises, and bus stations are considered high risk areas for biological warfare is because they all have a high number of people in them which means that there will be more fatalities.
Why would your heart rate increase or decrease to help maintain homeostasis when you exercise?
Answer:
The cardiovascular system helps to maintain homeostasis with respect to body temperature. An increased heart rate increases the delivery of blood to your skin. Increased blood flow to your skin and sweating causes dissipation of heat, and body temperature remains within normal limits.
Explanation:
Answer:
well here mate.
Explanation:
the reason i9s while exercising different exercises require different levels of energy therefor why you do push ups your heart rate will beat very fast depending on how long you have been doing them, and when you jog you are at a comfy speed there fore your heart rate stays low and calm.

In May 2018, the Kilauea volcano on Hawaii's Big Island began to erupt, spewing lava over part of the island.
Which event are Hawaiians most likely to observe first in the areas covered by lava?
A. Mosses will grow in thin, rocky soil.
B. Lichens will grow on the cooled lava.
C. Trees will grow in thick, rich soil.
D. Grasses will grow in soil with organic matter.
Primary succession occurs after the occurrence of a severe event that leaves nothing but rocky surfaces. Option B. Lichens will grow on the cooled lava.
What is succession?
The succession term refers to colonization and subsequent changes.
Colonization has been defined as the sequence of events that conduce to the establishment of individuals, populations, species, or bigger groups in areas where they were absent before.
Succession refers to changes produced in the composition and structure of communities after a perturbation. There are different grades of succession according to the perturbation intensity.
What is Primary succession?In primary succession, the perturbation is so intense that it eliminates all the life forms in the area.
It is the sequence of species appearance in an exposed area that has not been influenced by any other species or community before.
In these cases, the rock gets exposed but it can not be colonized directly. The new area needs to suffer erosion and different chemical and physical processes that fragment, degrade and dissolve the rock to make colonization possible.
Primary succession occurs after severe events affecting a region, such as a retreating glacier, a volcanic activity, or an intense fire that leave nothing but the exposed rock.
After the disturbance, the order of the living beings establishment depends on the strategies of each of the species to survive.
First, pioneer species arrive. These are the first inhabitants, mostly lichens or plants with the capability of surviving in such an environment. Only a few pioneers can establish in the open space.
Pioneers modify the habitat. They make it more suitable for the posterior establishment of later species, converting rock into fertile soil. As conditions get better, new species arrive like grasses.
Grasses and pioneers keep modifying the ground and making it better with time.
Habitat modification keeps on going while new species establish. They produce shadows and alter the temperature, and humidity, fertilizing the soil.
Competition becomes more frequent between species. The first species are eventually eliminated by competition, while new species keep appearing and competing for resources.
This sequence continues until there is no more facilitation, and the communities reache a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.
In the exposed example, the severe event affecting the Hawaii's Big Island was a volcanoe eruption.
The most likely event observed first in the areas covered by lava would be Lichens will grow on the cooled lava. Option B

Rain washing oily runoff from a road into a river that runs alongside the road is an example of point source pollution or nonpoint source pollution?
Help pls.
Answer:
This would be an example of nonpoint source pollution.
Explanation:
The source of point source pollution is typically factories and powerplants, leading to more air and water transferred pollutants and becoming easier to track. Nonpoint source pollution is the opposite of point-source pollution, with pollutants being released in a wide area. Since the rainwater would be washing the oils and particles into the water, it would be considered runoff. Runoff is one of the leading causes of point source pollution. I hope this helps. ^_^
What effect do the sulfate aerosols formed by volcanoes have on global temperatures?
Answer:
There is overall agreement that volcanic sulphate aerosols in the stratosphere can reduce solar radiation reaching the earth's surface for years, thereby reducing surface temperatures, affecting global circulation patterns and generally the global climate system.

2. Give a reason why earth worms come out of the soil when it has rained.
for wallowing it?
Explanation:
Oxygen diffuses easily through air, and the soil stays aerobic because oxygen comes in from the surface. But after a rain, the soil pores and the worm burrows fill with water. The worms can't get enough oxygen when the soil is flooded, so they come to the surface to breathe.

What types of health related issues might be associated with climate related factors?
A) malaria
B)
skin cancer
C) hypothermia
D) elevation sickness
E) all of the above
Answer:
E) All of the above
Explanation:
Malaria, is caused by mosquito bites, and mosquito's follow warmth, so if climate changes to warm really quickly more people are likely to get malaria. Skin cancer can be caused by sun radiation, or staying in the sun for to long, so if climate changes again to really warm, you can get skin cancer if not careful. If your to hot you can go in hypothermia shock. And if the elevation increases or decreases to quick you can get elevation sickness. All of these options change, because of the climate around them, therefore the answer is E. I hope this helps :)

A. Air pollution
B. Water Contamination
C. Exposure to radioactive elements
D. Spread of invasive species.
Answer: B
Explanation:
Answer:
C exposure to radioactive elements
Explanation:
The main concern of using nuclear power is the radioactive elements it creates. An example would be uranium.
Sure natural gas is bad for the environment but its no where near as harmful as exposure to radioactive
Drilling for oil does not release radioactive elements therefore exposure to radioactive elements can only be caused by nuclear power.
